1. xml转json

具体就不多说了，我是采用的笨方法，多次使用正则进行替换的。比较好的一点儿是支持xml元素属性。如果xml节点有属性会使用 @attributes:{属性列表} 进行格式化处理。如果有属性只有一个值，那值要采用@value:"值"进行格式化。代码如下：

/**     * 格式化为json格式     *      * @param result     * @return     */    public static String fmt2Json(String result){        if(validate(result)){            return result;        }        result = result.replaceAll(">\\s*<", "><").replaceAll("<\\?([^>|^\\?]*)\\?>", "");        String json = result;        Matcher matcher = Pattern.compile("<([^>|^/]*)>").matcher(result);        while(matcher.find()){            for (int i = 0; i < matcher.groupCount(); i++) {                String s = matcher.group(i+1);                json = json.replaceAll("<"+s+">([^<|^\"]*)
    ", "\""+s+"\":\"$1\",");            }        }        json = "{"+json.replaceAll(",?
    ", "},").replaceAll("<([^<]*)>", "\"$1\":{")+"}";        json =json.replaceAll(",}","}").replaceAll("(\\s*\\w*)=\"(\\w*)\"\\s*\"?", "\"$1\":\"$2\",")                .replaceAll("\\s+([^{]*),:" ,  ":{\"@attributes\":{\"$1},").replace("},{", "},")                .replaceAll("},([^}|^\"]*)}", "},\"@value\":\"$1\"}");        return json;    }

2. json转xml

/**     * 格式化为xml格式     *      * @param json     * @return     */    public static String fmt2Xml(String json){        return fmt2Xml(json, "root");    }    /**     * 格式化为xml格式     *      * @param json     * @param rootEle     * @return     */    public static String fmt2Xml(String json, String rootEle){        if(!validate(json)){            return fmt2Xml(fmt2Json(json),rootEle);        }        rootEle = rootEle.replaceAll("\\W", "");        rootEle = StringsUtil.isNullOrEmpty(rootEle)? "root": rootEle;//        return json.replaceAll("\"(\\w*)\":\"?([^\",}]*)\"?,?","<$1>$2
    ").replaceAll("\\{([^\\}]*)\\}", "
    <"+rootEle+">$1"+"
    ");        //去掉@attributes和@value        Pattern pattern = Pattern.compile("\"@attributes\":\\{([^}]*)}");        Matcher matcher = pattern.matcher(json);        int t =0;        while(matcher.find()){            t++;            String s = "";            for (int i = 0; i < matcher.groupCount(); i++) {                s = matcher.group(i+1);                s = s.replaceAll("\"(\\w*)\":\"([^\"]*)\",?", " $1=$2");            }            json = json.replaceAll("[^,]\"(\\w*)\":\\{\"@attributes\":\\{[^}]*},?","{\"$1"+s+"\":{");            //matcher = pattern.matcher(json);        }        json = json.replaceAll("\\{\"@value\":\"([^\"]*)\"}", "\"$1\"");        //处理嵌套        json = json.replaceAll("\"([\\w|\\s|=]*)\":\"([^\",{}]+)\",?", "<$1>$2
    ");        pattern = Pattern.compile("\"(\\w*)\":\\{([^{}]*)},?");        while(pattern.matcher(json).find()){            json = pattern.matcher(json).replaceAll("<$1>$2
    ");        }        pattern = Pattern.compile("\"([\\w|\\s|=]*)\":([^}\"]*)},?");        while(pattern.matcher(json).find()){            json = pattern.matcher(json).replaceAll("<$1>$2
    ");        }        json = json.replaceAll("(\\w*)=(\\w*)", "$1=\"$2\"").replaceAll("/(\\w*)\\s[\\w*)=\"\\w*\"\\s?]*", "/$1").replaceAll("[{|}]", "");        json = "
    <"+rootEle+">"+json+"
    ";        return json;    }

public static void main(String[] args) {        String str = "
    
     "                                + "
     
      201

      "                                + ""                                + "

    ";        String json = fmt2Json(str);        String xml = fmt2Xml(json);        System.out.println("xml转化为json：" + json);        System.out.println("json转化为xml：" + xml);    }

xml转化为json：{"Response":{"@attributes":{"a":"123","b":"000"},"status":{"@attributes":{"c":"123","d":"000"},"@value":"201"},"A":{"status1":"201","message1":"APP被用户自己禁用"},"A2":{"status1":"201","message1":"APP被用户自己禁用"},"B":{"BB":{"status1":"201","message1":"APP被用户自己禁用"}},"message":"APP被用户自己禁用，请在控制台解禁","C":{"status1":"201","message1":"APP被用户自己禁用"}}}json转化为xml：
